In Echoes I also feel like the complexity is too far out of reach for my mind. I can't keep in mind the forecasts, the echoes, the double achievements, the hand management, the new special achievements, the crazier dogmas, etc. etc. It's not as fun because it's not possible for me to internalize everything, like oh, if I am careful with the order in which I tuck with Lighting or Reformation, I can get one of the weird special achievements.
